CAS#: 22350-90-9

Description: Dactylarin is cytotoxic antibiotic. Dactylarin isolated from Dactylaria lutea (Deuteromycetes). Cytotoxic effect of dactylarin on Ehrlich ascites carcinoma cells is caused by the inhibition of some SH-dependent glycolytic enzymes, especially of hexokinase (EC, glyceraldehyde-3-phosphate dehydrogenase (EC and 6-phosphofructokinase (EC Dactylarin interacts with thiols, which explains its inhibitory effectiveness on the above glycolytic enzymes.
